Impactive Capital cofounder Lauren Taylor Wolfe told attendees at the Sohn Investment Conference that her firm is going to advocate for changes to Wyndham Hotels' energy use to increase the value of the hotel chains' stock. Wyndham, which includes brands like Days Inn and recently bought La Quinta Inns, is protected from new competition like AirBnB because of its low prices, Wolfe said. The fund believes improvements to the hotels' air-conditioning systems and lighting systems will both save the company money and help the environment.
